Substitute Part Grouping Explanation

Substitution of the CD4512BPW is determined by strict equivalence across the following critical parameters:

• Circuit configuration: 1 x 8:1 multiplexer topology
• Output current specifications: 6.8mA high and low
• Voltage supply range: 3V to 18V dual supply operation
• Operating temperature range: -55°C to 125°C
• Package and pinout: 16-TSSOP surface mount
• Series classification: 4000B logic family
• Compliance certifications: ROHS3, REACH Unaffected

The CD4512BPWR qualifies as a direct substitute based on identical electrical specifications and package configuration. The primary distinction between the main part and substitute is packaging format: tube versus tape & reel.

Parameter Comparison

Engineering Selection Recommendations

The CD4512BPWR is the direct functional equivalent to the CD4512BPW. Both parts share identical electrical characteristics, thermal performance, and physical package specifications. The CD4512BPWR maintains Active product status, providing continued manufacturer support and supply chain availability, whereas the CD4512BPW is designated Last Time Buy.

Selection between these parts should be based on procurement requirements and assembly processes. The CD4512BPW in tube packaging is suitable for lower-volume applications or manual assembly workflows. The CD4512BPWR in tape & reel format is optimized for automated pick-and-place assembly and high-volume production environments.

Both parts meet ROHS3 compliance and REACH regulatory requirements, ensuring suitability for applications subject to environmental and hazardous substance restrictions.

Frequently Asked Questions (FAQ)

Q: Can CD4512BPWR be used as a direct replacement for CD4512BPW?

A: Yes. Both parts are electrically and mechanically identical. They share the same 16-TSSOP pinout, voltage specifications, current ratings, and temperature range. The only difference is packaging format.

Q: What is the difference between tube and tape & reel packaging?

A: Tube packaging contains individual components in a plastic tube, suitable for manual handling and lower-volume assembly. Tape & reel packaging presents components on a continuous carrier tape wound on a reel, designed for automated assembly equipment. Both formats contain the same component.

Q: Why is CD4512BPW marked as Last Time Buy?

A: Last Time Buy status indicates the manufacturer is discontinuing this product. Existing inventory may be available, but no future production is planned. The CD4512BPWR in tape & reel format remains in active production.

Q: Are there any electrical performance differences between CD4512BPW and CD4512BPWR?

A: No. Both parts deliver identical electrical performance: 1 x 8:1 multiplexer configuration, 6.8mA output current capability, 3V to 18V dual supply operation, and -55°C to 125°C temperature range.

Q: Can these parts be used interchangeably in PCB assembly?

A: Yes, provided the assembly process accommodates the packaging format. Automated assembly lines typically require tape & reel format (CD4512BPWR). Manual or semi-automated processes can use either format. The 16-TSSOP pinout is identical.

Q: What compliance certifications apply to both parts?

A: Both CD4512BPW and CD4512BPWR are ROHS3 compliant and REACH unaffected, meeting environmental and hazardous substance regulations for industrial and commercial applications.
